I only wash my hair once a week but this blow dryer is a game changer. I have naturally wavy hair/frizzy  and this hair dryer completely made it silky smooth. I honestly am so happy with this product and totally recommend it to everyone. Also, it is beautiful in color and has all the necessary tools for any look that you are going for. My friends love it and have used mine and will be buying their own. I am so HAPPY!
